MySQL不会创建表格或用值填充它。

Question

在下面的代码中，我声明了一个游标，然后在创建一个表后不久。然后循环并向表中添加值：

DELIMITER //
DROP PROCEDURE IF EXISTS studentinfo//
CREATE PROCEDURE studentinfo()
BEGIN
 -- Declare local variables
 DECLARE done BOOLEAN DEFAULT 0;
 DECLARE studentNum INT(2);
 DECLARE gradepoint DECIMAL(3,2);
 DECLARE lastName VarChar(15);
 DECLARE classYear INT(1);
 -- Declare the cursor
 DECLARE studentNumber CURSOR
 FOR
 SELECT Student_number FROM student;
 -- Declare continue handler
 DECLARE CONTINUE HANDLER FOR SQLSTATE '02000' SET done=1;
 -- Create a table to store the results
 **CREATE TABLE IF NOT EXISTS studentdata(gpa DECIMAL(3,2), LName VarChar(15),class INT(1));**
 -- Open the cursor
 OPEN studentNumber;
 -- Loop through all rows
 REPEAT
 -- Get student number
 FETCH studentNumber INTO studentNum;
 -- Get gpa
 Select student_gpa(studentNum) INTO gradepoint;
 -- Get name
 Select LName from student WHERE Student_number = studentNum INTO lastName;
 -- get grade level
 Select Class from student WHERE Student_number = studentNum INTO classYear;
 -- Insert info into table
 **INSERT INTO studentdata(gpa,Lname,class)
 VALUES(gradepoint, lastName, classYear);**
 -- End of loop 
 UNTIL done END REPEAT;
 -- Close the cursor
 CLOSE studentNumber;
 END//
 DELIMITER ; 

当我然后从studentdata运行Select *时，它给了我一个表不存在＆＃39;错误。我可以通过运行创建表的一行代码手动创建表，但如果我运行整个代码块，它将不会创建它。即使我手动创建它，它仍然不会用任何值填充它。我在这做错了什么？感谢。
